# The pressure in the water supply pipes is 4 * 10/5 Pa to what height the water from the fire pipe connected

**The pressure in the water supply pipes is 4 * 10/5 Pa to what height the water from the fire pipe connected to this water supply will beat, if we do not take into account the air resistance and friction of the pipe.**

To solve this problem, it is necessary to find the height of the liquid column that creates the pressure P. For this, we use the formula known from physics. Where p = 1000 (kg / m3) is the density of the liquid. Where h is the height of the water column. Where g = 9.8 (m / s2) is the acceleration at the earth’s surface. Where P = 4 * 10 ^ 5 (Pa) – water pressure.

P = p * g * h. From here we find the height of the water rise.

h = P / (p * g) = (4 * 10 ^ 5 (Pa) / (1000 (kg / m3) * 9.8 (m / s2)) = 40.81 (m).

Answer: the height of the rise of water will be h = 40.81 (m).
